Salmon runs are difficult. Sometimes, you will be unlucky and there will be waves of complete chaos that overwhelm you faster than you think. You might have a map you don't really like, weapons you're not familiar with, and too many fish-firing missiles. Accept it as a loss.

You fail so many times in Salmon Escape, it's frustrating. However, you should accept that a wave has left you, deal with the losses accordingly, and then jump back in for another try -- whether it's the same player or something new because that could make all the difference.
